President Barack Obama sought to persuade Israeli President Benjamin Netanyahu Monday to hold off on attacking Iranian nuclear sites so economic sanctions can be given more time to set in. But in an evening speech just hours after his meeting with Obama, Netanyahu said time is running out for Israel to take out Tehran's nuclear weapons program.
Texas Republican Sen. John Cornyn cast the Iranian nuclear tensions as a race. In one lane are the U.S.-pushed sanctions that the administration says will take time to fully take effect and in the other lane is Iran's ability to field a weapon.
U.S. national security officials and lawmakers -- and, importantly, their Israeli counterparts -- say it is unclear how that race will play out.
